The above answer is according to the worksheet but I will present it in another way for you to understand better.
The figure has 5 sides
------------------------- Bottom Triangle ------------------------- Area = 1/2 x base x height Area = 1/2 x 8 x 3 Area = 12 ft²
------------------------- Top Triangle ------------------------- Top Triangle = Bottom Triangle Top Triangle = 12 ft²
------------------------- 3 Rectangles on the sides ------------------------- Area of 1st Rectangle = Length x Width Area of 1st Rectangle = 7 x 5 = 35 ft² Area of 2nd Rectangle = 7 x 5 = 35 ft² Area of 3rd Rectangle = 8 x 7 = 56 ft² Total area of the rectangles = 35 + 35 + 56 = 126 ft²
------------------------- Total Surface Area ------------------------- 126 + 12 + 12 = 150 ft²
<em>(*Area of the 3 rectangles + top triangle + bottom triangle) </em> ------------------------- Answer: 150 ft² -------------------------
